4. Functions of the UPS
4-3 Description of the auto battery tests
This UPS provides automatic checking functions whether a battery needs replacing and/or the internal circuit
is at fault. (You do not have to perform the tests by yourself.)
The tests are performed within 4 to 24 hours after the AC Input Plug is put in a wall outlet (commercial power)
on the ground that the UPS continues in usual service conditions. The test will be subsequently repeated every
4 weeks.
In a case where you remove the AC Input Plug from a wall outlet (commercial power) while the UPS is turned
off, the test period will be reset. When the UPS detects that the UPS is turned off, the battery needs replacing,
or the UPS enters in the backup mode within 4 hours after starting the test due to irregularities in the mains
supply, the test will not be performed.
In a case where you prefer to "disable the auto battery test," you can change the setting through the
UPS monitoring software. For further information, refer to the online help of the UPS monitoring
software. (The factory-shipped setting is "Enable the auto battery test.")
(1) When the auto battery test starts, your UPS enters automatically
into the battery mode. (No beep sounds.) After the completion
of the battery replacement test, the UPS automatically goes back
to usual service conditions.
(2) If the Error Lamp goes on and beeper sounds, take necessary
countermeasures according to "C. Failure (display and beep
when a failure occurs in devices)" of "3-3 Beep and display" on
page 27.
(3) If the Battery Replacement Lamp goes on and beeper sounds,
a battery needs replacing. Replace the battery according to "6-
2 Replacing the battery" on page 33.
Explanations
On the ground that the UPS is in usual service conditions, a self-test is performed automatically within 4 to
24 hours after the AC Input Plug is put in a wall outlet (commercial power).
In a case you turn off the UPS everyday, select the "Don't perform battery auto test" setting.
In a case you select "Perform battery auto test" setting, the estimated life expectancy of a battery pack will
become shorter as the battery test is repeated everyday.
